As required under Accounting Standards Update 2014-15, Presentation of Financial Statements-Going Concern (ASC 205-40), we have the responsibility to evaluate whether conditions and/or events raise substantial doubt about our ability to meet our future financial obligations as they become due within one year after the date the financial statements are issued. Based on our most recent projected cash flows, we believe that our cash and cash equivalents would not be sufficient to satisfy our anticipated operating and other funding requirements for the next twelve months from December 31, 2024. These factors raise substantial doubt regarding our ability to continue as a going concern. In addition, the report of our independent registered public accountant accompanying our audited consolidated financial statements included elsewhere in this prospectus contains a qualification to such effect.

Previous wording

We have incurred operating losses and negative cash flows since inception and had an accumulated deficit of approximately $44.3 million as of December 31, 2024. We expect to continue to incur operating losses and negative cash flows. Our operations have consumed substantial amounts of cash. We will require substantial additional funds to support our continued research and development activities, including the anticipated costs of nonclinical studies and clinical trials, regulatory approvals, and potential commercialization. Additionally, our estimates on future financial needs may be based on assumptions that prove to be wrong, and we may spend our available financial resources much faster than we expect. Because we expect to continue to experience operating losses, our ability to continue as a going concern is subject to our ability to obtain necessary capital from outside sources, including obtaining additional capital from the sale of our capital stock or other equity securities or assets, obtaining additional loans from financial institutions or investors, and entering into collaborative research and development arrangements or licensing some or all of our patents and know-how to third parties while retaining a royalty and other contingent payment rights related to the development and commercialization of products covered by the licenses. Our continued operating losses and the risks associated with the development of our product candidates and technologies have increased the difficulty in obtaining such capital, and there can be no assurances that we will be able to obtain such capital on favorable terms or at all. Furthermore, geopolitical instability, including the ongoing military conflicts between Russia and Ukraine and Israel and Hamas, as well as the impact of inflationary pressures and resulting rise in interest rates, on global financial markets could make the terms of any available financing less attractive to us and more dilutive to our existing stockholders. If we are unable to raise additional capital, we will have to delay, curtail, or eliminate one or more of our research and development programs or ultimately not be able to continue as a going concern. Additionally, raising additional capital may cause dilution to our stockholders.

All of our current product candidates are in preclinical development and will require substantial further capital expenditures, development, testing, and regulatory approval prior to commercialization. We have limited experience designing clinical trials and have not yet filed or supported a marketing application. We may be unable to design and execute a clinical trial that ultimately supports marketing approval.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or therapeutic product, if any, and us in general. In addition, the information we choose to publicly disclose regarding a particular nonclinical study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular therapeutic product, if any, product candidate or our business. If the preliminary, interim, and topline data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects, or financial condition.

Previous wording

As is the case with other biotech and pharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity, and are therefore costly, time consuming and inherently uncertain. Changes in either the patent laws or interpretation of the patent laws could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of our issued patents. For example, in March 2013, under the America Invents Act, the United States transitioned from a “first to invent” to a “first to file” patent system. Under a “first to file” system, assuming that other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to a patent on an invention regardless of whether another inventor had made the invention earlier. A third party that filed a patent application in the USPTO after March 2013, but before we or Legacy Serina filed could therefore be awarded a patent covering an invention of ours even if we or Legacy Serina had made the invention before it was made by such third party. This requires us to be cognizant of the time from invention to filing of a patent application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that it or any licensors were the first to either file any patent application related to our technologies or product candidates or invent any of the inventions claimed in our or our licensor’s patents or patent applications. The America Invents Act also includes a number of other significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted, allowing third-party submission of prior art, and establishing a new post grant review system, including post grant review, inter partes review, and derivation proceedings. Because of the lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use USPTO proceedings to invalidate our patent claims even though the claim would not have been invalidated if first challenged by the third party in a district court action.

In December 2021, Regulation No 2021/2282 on HTA amending Directive 2011/24/EU, was adopted in the EU. This Regulation, which entered into force in January 2022 and will apply as of January 2025, is intended to boost cooperation among EEA countries in assessing health technologies, including new medicinal products, and providing the basis for cooperation at the EEA level for joint clinical assessments in these areas. This Regulation foresees a three-year transitional period and will permit EEA countries to use common HTA tools, methodologies, and procedures across the EEA, working together in four main areas, including joint clinical assessment of the innovative health technologies with the most potential impact for patients, joint scientific consultations whereby developers can seek advice from HTA authorities, identification of emerging health technologies to identify promising technologies early, and continuing voluntary cooperation in other areas. Individual EEA countries will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technologies, and making decisions on pricing and reimbursement. If we are unable to maintain favorable pricing and reimbursement status in EEA countries for drug candidates that we may successfully develop and for which we may obtain regulatory approval, any anticipated revenue from and, growth prospects for, those products in the EEA could be negatively affected.

As of December 31, 2024, we had 13 full time employees and, in connection with the growth and advancement of our pipeline, we expect to increase the number of our employees and the scope of our operations, particularly in the areas of product development, business development, regulatory affairs, and sales and marketing. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational, and financial systems, expand our facilities, and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expected expansion of our operations or recruit and train additional qualified personnel. Moreover, the expected physical expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

We have material weaknesses in our internal control systems over financial reporting and will need to hire additional personnel and design and implement proper and effective internal controls over financial reporting commensurate with the accounting and reporting requirements of a public company. We may identify additional material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements. If we fail to remediate our material weaknesses, we may not be able to report our financial results accurately or prevent fraud. Our management is responsible for establishing and maintaining internal control over financial reporting, disclosure controls, and compliance with the other requirements of the Sarbanes-Oxley Act and the rules promulgated by the SEC thereunder.

Current wording

Our management is responsible for establishing and maintaining internal control over financial reporting, disclosure controls, and compliance with the other requirements of the Sarbanes-Oxley Act and the rules promulgated by the SEC thereunder. As a result of being a public company, we are required to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. A material weakness is a deficiency or combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual and interim financial statements will not be detected or prevented on a timely basis. We may identify material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements. If we fail to remediate such material weaknesses, we may not be able to report our financial results accurately or prevent fraud.

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. For example, in 2008, the global financial crisis caused extreme volatility and disruptions in the capital and credit markets and the COVID-19 pandemic has caused significant volatility and uncertainty in U.S. and international markets. See “Risks Related to Employee and Operations Matters, Managing Growth and Information Technology.” A pandemic, epidemic, or outbreak of an infectious disease, such as the COVID-19 pandemic, may materially and adversely affect our business and our financial results and could cause a disruption to the development of our product candidates. A severe or prolonged economic downturn, or additional global financial crises, could result in a variety of risks to our business, including weakened demand for our product candidates, if approved, or our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could also strain our suppliers, possibly resulting in supply disruption. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

For the tax years beginning on or after January 1, 2022, the Tax Cuts and Jobs Act of 2017 (“TCJA”) eliminates the option to currently deduct research and development expenses and requires taxpayers to capitalize and amortize them over five years for research activities performed in the United States and 15 years for research activities performed outside the United States pursuant to IRC Section 174. Although Congress is considering legislation that would repeal and defer this capitalization and amortization requirement for research activities performed in the United States, it is not certain that this provision will be repealed or otherwise modified. If the requirement is not repealed or replaced, it will continue to defer our tax deduction for research and development expense in future years.

On July 4, 2025, the U.S. Congress enacted the One Big Beautiful Bill Act, which includes provisions that allow for the immediate expensing of domestic U.S. research and development expenses, a general requirement to reduce the deduction for research and development expense by any research credit taken, and other changes to the U.S. taxation of profits derived from foreign operations. We have no assurance as to whether, when and how these provisions may be subject to further amendment or repeal. Such changes, among others, may adversely affect our effective tax rate, results of operation, and general business condition.

The invasion of Ukraine by Russia and the sanctions, bans and other measures taken by governments, organizations and companies against Russia and certain Russian citizens in response thereto has increased the political uncertainty in Europe and has strained the relations between Russia and a significant number of governments, including the United States. Any retaliatory actions taken by Russia, the duration and outcome of this conflict and the conflict among Israel, Hamas and Hezbollah, and the impact on regional or global economies is unknown but could have a material adverse effect on our business, financial condition and results of our operations.

The U.S. government has made statements and taken actions in recent years that have led to certain changes and may lead to additional changes to U.S. and international trade policies, including imposing several tariffs affecting certain products manufactured in China, Canada and Mexico. It is unknown whether and to what extent new tariffs (or other new laws or regulations) will be adopted, or the effect that any such actions would have on us or our industry. Any unfavorable government policies on international trade, such as export controls, capital controls or tariffs, may affect the use of testing facilities in China that we use, including pursuant to our testing arrangements with WuXi AppTec (HongKong) Limited. If any new tariffs, export controls, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated or, in particular, if the U.S. government takes retaliatory trade actions due to the recent U.S.-China trade tension, such changes could have an adverse effect on our business, financial condition and results of operations.

Current wording

The U.S. government has made statements and taken actions in recent years that have led to certain changes and may lead to additional changes to U.S. and international trade policies, including imposing tariffs on a variety of countries and products. Historically, tariffs have led to increased trade and political tensions. In response to tariffs, other countries have implemented retaliatory tariffs on U.S. goods. Political tensions as a result of trade policies could reduce trade volume, investment, technological exchange, and other economic activities between major international economies, resulting in a material adverse effect on global economic conditions and the stability of global financial markets. There is substantial uncertainty about the duration of existing tariffs and whether additional tariffs may be imposed, modified, or suspended, or the effect that any such actions would have on us or our industry. Any unfavorable government policies on international trade, such as export controls, capital controls or tariffs, may affect the use of testing facilities in China that we use, including pursuant to our testing arrangements with WuXi AppTec (HongKong) Limited. If any new tariffs, export controls, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated or, in particular, if U.S. trade policy results in retaliatory trade actions, such changes could have an adverse effect on our business, financial condition and results of operations.

We will incur significant legal, accounting and other expenses that Legacy Serina did not incur as a private company, including costs associated with public company reporting requirements. We will also incur costs associated with corporate governance requirements, including requirements under the laws, rules and regulations of the SEC as well as the NYSE American rules. These laws, rules and regulations are expected to increase Legacy Serina’s legal and financial compliance costs and to make some activities more time consuming and costly. These executive officers and other personnel will need to devote substantial time to gaining expertise regarding operations as a public company and compliance with applicable laws and regulations. These laws, rules and regulations also may make it difficult and expensive for us to obtain directors’ and officers’ liability insurance. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our Board or as our executive officers, which may adversely affect investor confidence in us and could cause our business or stock price to suffer.

The trading market for our common stock will be influenced by the research and reports that equity research analysts publish about it and our business. Equity research analysts may elect not to provide research coverage of our common stock after the completion of the Merger, and such lack of research coverage may adversely affect the market price of our common stock. In the event we do have equity research analyst coverage, we will not have any control over the analysts, or the content and opinions included in their reports. The price of our common stock could decline if one or more equity research analysts downgrade our stock or issue other unfavorable commentary or research. If one or more equity research analysts ceases coverage of us or fails to publish reports on us regularly, demand for our common stock could decrease, which in turn could cause our stock price or trading volume to decline.

We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act and the rules and regulations of the NYSE American. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting in our Annual Report on Form 10-K filing for that year, as required by Section 404 of the Sarbanes-Oxley Act. As a private company, Legacy Serina was never required to test its internal controls within a specified period. This will require that we incur substantial professional fees and internal costs to expand our accounting and finance functions and that we expend significant management efforts. We may experience difficulty in meeting these reporting requirements in a timely manner.

Following the Merger, we had a public float of less than $250 million and therefore qualify as a smaller reporting company under the rules of the SEC as of the date of this prospectus. As a smaller reporting company, we will be able to take advantage of reduced disclosure requirements, such as simplified executive compensation disclosures and reduced financial statement disclosure requirements in our SEC filings. Decreased disclosures in our SEC filings due to our status as a smaller reporting company may make it harder for investors to analyze our results of operations and financial prospects. We cannot predict if investors will find our common stock less attractive if it relies on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile. We may take advantage of the reporting exemptions applicable to a smaller reporting company until we are no longer a smaller reporting company, which status would end once we have a public float greater than $250.0 million. In that event, we could still be a smaller reporting company if our annual revenues were below $100.0 million and we have a public float of less than $700.0 million.

New tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business, prospects, financial condition and operating results. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, the Tax Act, the CARES Act, and the IRA enacted many significant changes to the U.S. tax laws. Future guidance from the IRS and other tax authorities with respect to such legislation may affect us, and certain aspects of such legislation could be repealed or modified in future legislation. Such tax law changes could have a material adverse impact on us. In addition, it is uncertain if and to what extent various states will conform to newly enacted federal tax legislation. While it is too early to assess the overall impact of these changes, as these and other tax laws and related regulations are revised, enacted, and implemented, our financial condition, results of operations, and cash flows could be materially adversely impacted.

Such tax law changes could have a material adverse impact on us. In addition, it is uncertain if and to what extent various states will conform to newly enacted federal tax legislation. While it is too early to assess the overall impact of these changes, as these and other tax laws and related regulations are revised, enacted, and implemented, our financial condition, results of operations, and cash flows could be materially adversely impacted.

Previous wording

We have incurred losses during our history, and we do not expect to become profitable in the near future and may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire, if at all. As of December 31, 2024, we had U.S. federal NOL carryforwards of $87.8 million, which will begin to expire in 2027 and $63.1 million that have an unlimited carryforward period. Additionally, for state income tax purposes, we had NOLs of $56.1 million that will expire at various dates between 2025 and 2043. The state of California suspended the use of NOL deductions for the tax years 2024 through 2026 if their California taxable income is greater than or equal to $1 million. The state of California also limited the use of research and development credits to $5 million for tax years 2024 through 2026. Under current law, U.S. federal NOL carryforwards generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such NOL carryforwards is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to federal law. In addition, under Sections 382 and 383 of the Code, federal NOL carryforwards and other tax attributes may become subject to an annual limitation in the event of certain cumulative changes in ownership. An “ownership change” pursuant to Section 382 of the Code generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Our ability to utilize our NOL carryforwards and other tax attributes to offset future taxable income or tax liabilities may be limited as a result of ownership changes, including potential changes in connection with the Merger or other transactions. Similar rules may apply under state tax laws. If we earn taxable income, such limitations could result in increased future income tax liability to us, and our future cash flows could be adversely affected.
